Solar activity was at very low levels. The largest flare was a B8 from Region 456 (S07W45) at 12/2000Z. A long duration B7 X-ray enhancement occurred at 11/2237 and was correlated with the two disappearing solar filaments. The first DSF was five degrees long and lifted off around 11/2100Z near S25E05. The second DSF followed the first and was along the same inversion line. This DSF was about ten-degrees long and lifted off near S18E15. LASCO C2 imagery indicates a partial halo CME associated with the DSF's.

Solar activity is expected to be at very low to low levels.

The geomagnetic field was at quiet to unsettled levels. Solar wind speed remains elevated near 600 km/s and Bz has been predominantly northward.

The geomagnetic field is expected to be at quiet to active levels. Activity on day one and day two is expected to be quiet to unsettled. CME effects are possible on day three with activity expected to be at unsettled to active levels.
